This double chocolate banana bread turns those spotty bananas into a luxurious treat that sits right between casual snack and rich dessert. It's moist, chocolaty to the max, and brings all the warmth of regular banana bread with an extra hit of chocolate goodness that'll keep you coming back for more.
I've baked this bread dozens of times to get it just right. The secret's in getting your ingredients to the right temperature and mixing them the correct way. The first time my buddies tried it, they were shocked it started with old bananas!
Key Components
- Bananas: Need those really dark, spotty ones - they'll give you the best sweetness and moisture
- Unsweetened cocoa powder: Go for quality and freshness - Dutch-process makes the biggest difference
- Room temperature butter: Helps everything mix right - too firm or too melty messes up your texture
- Sour cream: Adds that nice smoothness and kicks the baking soda into gear
- Hot water: Wakes up the cocoa flavor, making the chocolate taste deeper

Making It Happen
- Step 1:
- Get your pan ready first - butter it well and put parchment paper in with extra hanging over the sides. This'll make taking it out super easy.
- Step 2:
- Smash those bananas until they're completely smooth. You'll want about 1½ cups from four medium ones. The smoother you get them, the better your bread texture.
- Step 3:
- Beat your room temp butter and sugar together until it looks light and fluffy, which takes around 3-4 minutes. Don't cut this short - it's what gives your bread that perfect bite.
- Step 4:
- Put in eggs one by one, mixing well after each. Remember to scrape the bowl sides often so everything mixes evenly.
- Step 5:
- Mix flour, cocoa powder, baking soda, and salt in another bowl through a sifter. This gets rid of lumps and spreads the baking soda throughout.
- Step 6:
- Add your dry stuff to the wet stuff bit by bit, switching between hot water and sour cream. Just mix until it comes together - mixing too much will make your bread tough.
- Step 7:
- Stir in most chocolate chips by hand, but save some to sprinkle on top.
- Step 8:
- Pour everything into your pan and bake at 350°F for about 60-65 minutes. It's done when a toothpick comes out with just a few wet crumbs.

I got this idea from my grandma's old banana bread recipe but kicked it up with double chocolate to make something extra special.
Nailing The Texture
After tons of tries, I've found that getting that fudgy feel depends on a few things. Measuring everything carefully. Mixing things in the right order. Getting your oven temp just right. Letting it cool properly.
Watching Your Heat
Pay attention to temperature at these points. Eggs and butter need to be room temp. Water should be hot but not boiling. Oven must be fully heated. Let the bread cool all the way before cutting.
Fixing Common Problems
Got baking troubles? Try these quick solutions. Bread too heavy? Check if your baking soda is fresh. Middle sinking? Keep that oven door closed. Chocolate chips all at bottom? Roll them in flour first. Stuck to the pan? Use parchment paper with flaps.
Try These Twists
Want to mix it up while keeping the basics? Add some espresso powder for richness. Mix in a swirl of tahini or almond butter. Throw in some toasted walnuts. Grate in some orange peel.
Keeping It Fresh
To make it last longer. Let it cool completely before wrapping it up. Use plastic wrap then foil for freezing. Put wax paper between slices. Warm it up before eating.
I've made this bread countless times, and what I love most is how flexible it is. You can have it with coffee in the morning, as a snack in the afternoon, or warmed up with ice cream for a fancy dessert.
More Ways To Use It
This bread can do more than just be a loaf. I've turned it into small loaves for gifts. Made muffins for grab-and-go snacks. Tried it as a bundt cake. Even used the batter for layer cakes.
The Art of Serving

Make it look fancy with. A drizzle of melted chocolate. Some fresh raspberries or strawberries. A dollop of whipped mascarpone. Sprinkle of toasted coconut. Some candied pecans.
Serving Temperature Tricks
How warm or cold you serve it changes everything. Room temp works best for breakfast. Slightly warm makes it dessert-worthy. Chilled gives you a denser bite. Toasted with a pat of butter is amazing.
Using Up Leftovers
Got some going stale? Turn it into bread pudding. Layer it in a trifle. Make amazing french toast. Create ice cream sandwiches with slices.
After baking this bread for years and seeing so many happy faces, I think of it as more than just food - it's a starting point for creativity and a way to make memories. Whether you're whipping it up for a birthday or just using bananas that are about to go bad, each loaf brings both comfort and a bit of celebration to the table.
